York Flame Rollout Switches

Overview

The Source1 2527747016 is a rollout control designed for gas furnaces and heating systems. It is a manual reset safety switch that opens at 320 degrees Fahrenheit. HVAC technicians use this control to protect furnaces from dangerous heat rollout conditions. Heat rollout occurs when flames or extremely hot gases escape the combustion chamber and spread into areas of the furnace where they should not be. This creates a fire hazard and can damage the heat exchanger, burner assembly, and surrounding components. The rollout control acts as a thermal fuse-style safety device mounted near the burner compartment. When the surrounding temperature reaches 320 degrees Fahrenheit, the switch opens and interrupts the circuit to the gas valve or ignition system. This shuts down the burner before damage or fire can occur. Because this is a manual close model, the control does not automatically reset after it trips. A technician must physically press the reset button to restore operation. This manual reset requirement is intentional. It forces an inspection before the system is restarted. A tripped rollout control is a warning sign. It typically points to a cracked heat exchanger, blocked flue, dirty burner, or restricted airflow. The Source1 2527747016 is a direct replacement part compatible with furnaces that use a 320-degree open, manual reset rollout switch. It is built to meet OEM-equivalent performance standards. HVAC service professionals keep this part on hand for furnace repair…
